Archips semiferanus (also known as Archips semiferana and Capua semiferana ) is a species of moth in the family Tortricidae, and one of several species of moth commonly known as Oak leafroller or Oak leaf roller. The larvae feed on the leaves of oak trees in the Eastern United States and southeastern Canada and are a major defoliator of oak trees, which can lead to tree mortality. In Pennsylvania in the late 1960s and early 1970s, Oak leafrollers defoliated over 1,045,000 acres (423,000 ha) and over $100,000,000 of timber was lost.
